While on shore leave on the planet Argelius II with Dr. McCoy and Captain Kirk, Chief Engineer Scott finds himself accused of murdering an exotic dancer he met in a nightclub. He has no recollection of the incident but is found standing over the girl with a bloody knife in his hand. For Mr. Hengist, the chief administrator, the case is cut and dried, but Jaris, the planet's leader, suggests that his wife chair a séance to identify the killer. Tragedy strikes again, still pointing to Mr. Scott as the culprit. Kirk suggests they retire to the Enterprise where they can use its computers to determine if Scott is lying and who the real culprit may be. Written by garykmcd

Did You Know?


For most of Star Trek, James Doohan ("Scotty") hides his right hand, which was missing the middle finger due to a WWII D-Day injury. While being questioned with his hand resting on some sort of lie detector scanner, his fingers are hidden by being curled around the edge of the plate. During a close-up shot of the machine reacting to an intentional lie being told, a complete five-fingered hand spread across the plate is seen - the hand is an obvious stunt double. See more »

Another Trial
29 April 2014 | by (United States) – See all my reviews

On an R & R trip to a peaceful planet where violence is unheard of, Scottie takes a walk with a beautiful courtesan, only to be discovered, knife in hand, over her body. He is arrested and set for trial. A whiny prosecutor named Hengist assumes Scottie's guilt. A young woman is beamed down to assist with the investigation. She takes Scot into a briefing area. While she questions she is killed and Scot lies, unconscious near the body. The prefect of the city and his wife offer to hold a kind of séance where his wife, who has some sort of clairvoyant gift is to get to the truth. Unfortunately, during the séance, the lights go out and the woman is standing, knife in the back, Scottie standing behind her, blood on his hands. Kirk knows that the ship's computer can determine guilt or innocence. The prefect goes along with it, bringing two witnesses and Hengist with him. One weird thing is that the prefect doesn't seem terribly upset about the death of his wife. Still he wants to get to the truth. It isn't long before some interesting data begins to appear. Mr. Hengist is quite combative through the whole thing. This is the third trial of one of the principle characters. This episode is entertaining and fun. The failing is that people don't seem to react very strongly to the deaths of their colleagues.
